Penguins coach Dan Bylsma would not name his starting goaltender for Game 6 tonight in New York, but it sounded as if it again will be Tomas Vokoun.Bylsma sang the praises of his veteran backup, whose calming presence was impossible to miss in Game 5 of the team's Stanley Cup playoff series against the New York Islanders."The lineup will not be discussed. But we know what Tomas did [Thursday] night in the game and how well he's played for us," Bylsma said Friday in his media conference call.Vokoun turned away 31 shots in a 4-0 victory that gave the Penguins a 3-2 lead in the series. It was Vokoun's first playoff appearance since 2007 when he was with the Nashville Predators.Game 7 time setThe NHL said on its website Friday that Game 7 of the Penguins-Islanders playoff series, if necessary, will start at 7 p.m. Sunday.The Penguins lead, 3-2, and could win the series by beating the Islanders Saturday night on Long Island. A Game 7 Sunday at Consol Energy Center would be necessary if the Penguins lost tonight.Taste of the playoffsNo fewer than 13 Islanders have made their Stanley Cup playoff debuts in this series, and some have conflicting views about just how much the postseason differs from regular-season play.Some, such as center Frans Nielsen, don't get what all the fuss is about."You have to keep your head up a little longer [in the playoffs] after you make a pass because there might be some late hits," he said. "But other than that, it's the same team we saw in the regular season. Not a big difference."But Wingers Matt Martin and Colin McDonald don't share his perspective. Not entirely, anyway."The physicality is obviously higher," Martin said. "It gets a lot chippier out there. Frustrations, emotions, run a little higher."But, for the most part, it's really just the crowds and the excitement from fans. Obviously, they're into it a lot more. Our arena is full. It's amped up a bit, but, at the end of the day, what we learned from the first game is that it really is the same game. The game we've been playing all along."McDonald believes it's obvious that the stakes and intensity are higher in the postseason."There's a difference," he said. "Guys and teams are fighting for their lives every game. The pace is a lot higher, the physicality is a lot more.
